Performance of an optimized nutrient management system for double-cropped wheat-maize rotations in North-Central China
Overapplication of N and P and insufficient supply of K are considered primary reasons for restriction of yield improvement in the North China Plain. Optimized nutrient management practices based on soil testing and yield targets have been developed. Other large scale field experiments have indicated that additional improvement for yield and nutrient use benefits is needed. The objective of this ...

Nitrogen contribution from red clover for corn following wheat in western Ohio
Inclusion of a winter legume cover crop into a crop rotation has been suggested as a method to provide a substantial portion of the N requirement of the following crop. While the benefits of winter cover crops such as reduced soil erosion, increased soil organic matter, and increased mulch cover have been well documented, the N contribution to the subsequent crop has shown to be variable. The ...

Zimbabwe`s New Farmers Fail to Deliver
HARARE, Zimbabwe, (ENS) - Six years after President Robert Mugabe sanctioned violent invasions of Zimbabwe's commercial farmland - mostly but not entirely white owned - by landless peasants, the facts show that the so-called new farmers have failed dramatically to produce crops to feed their countrymen. The poor peasants who led the invasions, at the behest of Mugabe, have since been driven ...

One crop, two ways, multiple benefits
Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

Cropland management techniques for carbon storage
The Kyoto protocol of 1997 recognises cropland management as a carbon sequestration strategy which may help to mitigate climate change. Under the protocol, ratified by the EU in 2002, member states are obliged to reduce the sum of their emissions of greenhouse gases to 5 per cent below their 1990 levels. Appropriate cropland management may help member countries meet the overall EU emissions ...

Top Dressing Fertilizer in Western Canada
Western Canada has a short growing season which makes another pass for top dressing fertilizer sometimes difficult to achieve. Many crops have the fertilizer applied during the seeding season with Liquid Distribution Systems, (like these kits we make here). Often this will meet the crops fertilizer requirements for the whole season. Making one pass makes sense in a season that brings the right ...
